Stunned to discover river fossils on Mars

A group of strange stretches of objects suspected to be fossils of a river that has just been discovered on Mars makes astronomers astounded.

Accordingly, this group of objects was discovered in an ancient geological crush on Mars. The fossil record suggests that this may be a river, estimated to be 17,000 km long in the North Martian plain called the Arabia Terra area. This continues to be evidence that Mars once had liquid water in the past .

It is possible that this river had been active in the past at a time of about 4 billion years ago, at which time Mars had a rather humid climate, not as cold and dry as it is today. Information from the British Space Science and Technology Agency said.

However, this is not the first time scientists have found traces of liquid on Mars in the Arabia Terra plains. In 1970, scientists from NASA's Reconnaissance Orbiter (MRO) spacecraft also found many strange, peculiar carvings that could be caused by the effects of rainwater and running water on the surface.

Return to the story of the fossil river that was found on Mars. This fossil is made of sand and gravel, they are concentrated and cling to mineral soil then fossilized when the river dried up and experienced for billions of years.

According to the estimated measurement, this river can be 30 meters deep, 1-2 km wide, it is a real remnant of a giant river, operating at about 3.7 billion - 3, 9 billion years ago on the surface of Mars. Researcher Joel Davis said in a statement.

The ancient river fossil suspect object group on this Mars is causing a stir among international astronomers.
